the other day i was walking back home from the hdb hawker centre then an old lady in her 70s was sitting on the roadside bench. as i passed her, she called out to me and asked if I could help her by providing my arm to support her to walk back to her hdb block. i obliged. she really couldn't walk steadily and after 10mins of providing my arm support for her, we finally reached the lift lobby of her hdb block. during our journey, i asked her what if nobody had walked passed then how? she said wait lor. wait until someone willing to help her. i asked why she didn't get a mobility electric wheelchair or pma. she said don't want to waste money. quite sad...
